My 98 S70, non turbo has now stalled twice on me, both times after being on the highway. Driving with the A/C on, the car felt a little jerky on the highway, but kept going, after I got off, and came to a stop at a red light, the rpm's would drop, car would shudder and stall. Any advise what it could be.

 

Well have a $500 tune up done and that seemed to solve the issue

 

Y'know I have the same issue currently. I did the tune-up and it didn't go away. The car still stalls once in a while. I'm going to change the MAF sensor...I looked into it with other people on-line and that seems to be it.

 

Is changing the MAF sensor expensive?

 

My 98 S70 was doing the same thing -- stalling -- I just took it to a mechanic and they said it was the MAFsensor. It cost about $350 to replace.
